Ways to Fix Java Virtual Machine Launcher Error

If you are not able to access Java Virtual Machine launcher on your Windows 10 or Windows 11 then you’re in the right place. Here, we have listed the effective methods you can check out to address the error on Java Virtual Machine launcher. By reading and applying the methods, you will be back to run Java Virtual Machine launcher again.

1. Run Java as an Administrator

If you are unable to access the Java Virtual Machine launcher on a Windows computer, it could be due to insufficient user privilege. To avoid the error, you should run the Java program as an administrator which allows you to run the program with administrator privileges.

To run Java as an administrator, follow the steps below:

3. Once you locate the Java file then right-click on it and select “Run as administrator.”
4. Under the User Account Control (UAC) menu, click Yes to proceed further.

2. Verify Java Installation

Another thing you have to do is verify Java Installation on your Windows laptop or PC. It is most important to install the right Java Runtime Environment (JRE) or Java Development Kit (JDK) tool. However, you may address the “Could Not Create the Java Virtual Machine” error on Windows computer if you’ve installed an incorrect program.

Make sure to check the necessary components and verify the installation of the Java program and other tools. Plus, ensure to check the system PATH environment variable to endorse that it includes the right Java directory. To check the Java Installation whether it is correctly placed or not, follow the steps below:

4. Next, type the below command and then click Enter to run it.

java --version

After entering the command, you will see the message on the screen. If you see “Could Not Create the Java Virtual Machine” error, then it means that Java Installation is incorrect. On the other hand, if you see the details about the Java version and its path, it means you’ve installed the correct Java and other programs.

3. Increase System Memory for Java

At certain times, the Lava Virtual Machine launcher shows the error message due to the Java program lacking memory. Generally, the memory allocated to Java is called a Java heap. Luckily, you can solve the Java error message by increasing system memory for Java. Below we have outlined the two most effective steps to increase system memory for Java programs.

Method 1: Increase Java Heap Size by Modifying Variables
